The original publication of the article reported polarized FTIR spectra taken on oriented superhydrous phase B crystals. Unfortunately, the authors mixed up the crystallographic c- and a-axes during their measurement. The atomic coordinates for hydrogen H2 should be x = 0.45; y = 0.18; z = 0.27. Thus, spectra in Fig. 10a are taken on the (001) plane with E parallel b (0°) and spectra in Fig. 10b are taken on the (010) plane with E parallel c (0°).
